When you open the shower, cold and unused water initially flows away into the sewer system. This can be up to 15 liters per minute, resulting in 20 800 liters per year when using a rain shower. At Smartstream, we offer a unique and problem-solving product not yet on the market. Our smart valve, built in front of the shower head, is going to ensure that this pure water is not lost. There are two possible scenarios for the water. If the water is below the desired temperature, it is diverted through our valve to the cistern. Once the water reaches its ideal temperature, our valve switches and the water flows out of the shower head.
